09 Accord Serpentine Belt
 

So I have an 09 accord lx and I’m trying to replace the serpentine belt. The tensioner is supposed to have a hex bolt like piece protruding from it to grab onto correct??? And if so, what if that protrusion isn’t there? I’m looking at it now and it appears to just be a hole where the bolt should be? Am I not looking at the tensioner? Please help asap it’s super hot and I’m out in the open this is crazy Iv attached a video of what I’m talking about
